At a certain company, some of the employees have advanced degrees, some have one year or more of work experience, and some have both. If 20 percent of all employees have one year or more of experience and no advanced degree, what percentage of employees have advanced degrees and less than one year of experience?
(1) 35 percent of the employees do not have advanced degrees and 55 percent have less than one year of work experience.
(2) 15 percent of the employees do not have advanced degrees and one year or more of work experience, but 45 percent have one year or more of experience.

I struggled with this question at first but think I got the answer!
Here is what I had to start with based off given info. Since we are dealing with %s, I thought it would be best to make up a # for total employees since none was given. I'm going with 1,000.
Total # of employees: 1,000 (not given, using it to plug in)
% with adv. degrees: this is the answer we need
% with 1+yr. exp: 20% of total employees, or 200
% both: ??? not given
% neither: ??? not given
Statement 1: not sufficient
We find out how many do not have adv degrees and were given the % with 1+ yr exp and no adv degree, we can find the % that have neither by doing 35% - 20% = 15%.
Total # of employees: 1,000 (not given, using it to plug in)
% with adv. degrees: this is the answer we need
% with 1+yr. exp: 20% of total employees, or 200
% both: ??? not given
% neither: 15%, or 150
We cannot find out the % with adv degrees and less than 1 yr exp with this info. Not sufficient. Eliminate answer choices A and D.
Statement 2: sufficient
This statement tells us the % that have neither. It also tells us that 45% have more than 1+yr exp. Since we already know how many have only 1+yr exp, we can do 45%-20%=25% to find the % that have both 1+yr exp and adv degrees. Since we have all of the values, we can find that 40% of the employees have adv. degrees.
Total # of employees: 1,000 (not given, using it to plug in)
% with adv. degrees: since we know all of the other #s, we know that the this value is 400 or 40%
% with 1+yr. exp: 20% of total employees, or 200
% both: 25%, or 250
% neither: 15%, or 150

Let A be % of people with advanced degrees and less than one year of experience. We need to find this value
W be % of people with no advanced degrees and with one year or more of work experience.
B be % of people with advanced degrees and with one year or more of work experience
N be % of people with no advanced degree and less than one year of experience
We know 100 = A+W+B+N, also W = 20
Statement 1:
We can say W+N = 35, A+N = 55
Since W= 20, we can say N = 15, Therefore A = 55-15= 40. Sufficient
Statement 2:
N = 15
W+B = 45
From this, we can say A= 100 - 15 - 45 = 40. Sufficient
Hence the answer should be D
W be % of people with no advanced degrees and with one year or more of work experience.
B be % of people with advanced degrees and with one year or more of work experience
N be % of people with no advanced degree and less than one year of experience
We know 100 = A+W+B+N, also W = 20
Statement 1:
We can say W+N = 35, A+N = 55
Since W= 20, we can say N = 15, Therefore A = 55-15= 40. Sufficient
Statement 2:
N = 15
W+B = 45
From this, we can say A= 100 - 15 - 45 = 40. Sufficient
Hence the answer should be D
